Use this professional ABIM Score Percentile Calculator to determine your ranking in the Internal Medicine Board Exam. By inputting your scaled score, the peer group mean, and standard deviation, you can instantly find your percentile standing compared to other candidates.
ABIM Score Percentile Calculator
Please enter at least 3 variables to calculate the missing one.
ABIM Score Percentile Calculator Formula:
The calculation is based on the Normal Distribution (Z-score) formula:
Z = (S - M) / SD
Where Percentile = Φ(Z) × 100

Variables:
- Scaled Score (S): The specific numeric score you received on your exam.
- Mean Score (M): The average score of all first-time takers from US medical schools in a given year.
- Standard Deviation (SD): A measure of how much scores vary from the mean.
- Percentile: The percentage of candidates who scored lower than you.

What is ABIM Score Percentile Calculator?
The ABIM Score Percentile Calculator is a statistical tool designed for physicians who have completed the American Board of Internal Medicine (ABIM) certification or MOC exams. Since ABIM reports scores as “scaled scores” (typically ranging from 200 to 800), it can be difficult to visualize your relative performance.
By converting your score into a percentile rank, you gain a clearer understanding of your standing within the medical community. This is particularly useful for fellowship applications or benchmarking your knowledge against national standards.
How to Calculate ABIM Score Percentile (Example):
- Identify Variables: Let’s say your score (S) is 500, the Mean (M) is 400, and the SD is 100.
- Calculate Z-Score: (500 – 400) / 100 = 1.0.
- Find Percentile: A Z-score of 1.0 corresponds to approximately the 84th percentile.
- Interpretation: You scored higher than roughly 84% of your peers.
Frequently Asked Questions (FAQ):
What is a passing ABIM score? The passing score is determined by the ABIM committee and typically falls around the 350-400 range, but it varies by year.
How often is the ABIM Mean updated? The ABIM updates its statistical data annually based on the performance of the first-time test-taker cohort.
Can I calculate my percentile without the Standard Deviation? No, the SD is crucial for determining the spread of scores. Most candidates use a historical SD of 100 as an estimate.
Is the percentile rank included in the official report? Yes, the official ABIM score report usually provides your percentile rank relative to first-time takers.
